Remedial
Depending on the causes of staining, different measures can be taken to mitigate its influence. In most cases, only cleaning work is needed.
The procedures for cleaning glazed surfaces begins by wringing out a cloth, sponge, or chamois till almost dry before wiping the glass surface (Figure 1).
The wet surface is then dried with newspapers, paper towels, window wipes, or a chamois. Avoid washing windows in direct sunlight because they tend to streak and are more difficult to clean.
However, if the staining is caused by the degradation of sealant, the replacement of defective sealant is needed.
